Push/Pull Tool – Move Face Mode – I use this tool to stretch, change, or edit 3D objects. As the name suggests this tool is used to push or pull 3D objects. This tool can be used to add or subtract solids, and you can use it to edit only a portion of the object.
The second mode moves the face. Unlike the first mode, this one moves the face in the same direction so that the sides of the object continue and the shape of the face changes accordingly.There is some great protected information here that is only available to paying subscribers.
